The only similarity to an LS6 motor that the '02 LS1 has is the intake manifold and some had the LS6 block as well. The true LS6 has a more aggresive cam and the 243 heads which outflow the 241's. Also the LS6's have slightly larger injectors (28.8#).

ok thanks guys.

so on a similar topic....

i am looking for a pretty mild cam and doing a set of rr's.

i want something around 380 rwhp. would the ls6 cam do that for me or what would you guys recommend for me?

the reason i only want around that power is so i dont have to worry about me 10 bolt breaking.
